The fuse cell circuit includes nor gate NOR, fusing NMOS tube N1, detection NMOS tube N2, switch NMOS tube N3；
The output end of nor gate NOR is connect with the grid of fusing NMOS tube N1, determines whether fuse fuses；The source electrode of the NMOS tube that fuses N1
The drain electrode of ground connection, fusing NMOS tube N1 is connected with the negative terminal of fuse FUSE, and the negative terminal of fuse FUSE is defined as A points；Detection
The drain electrode of NMOS tube N2 is connected with the negative terminal of fuse FUSE, and the drain electrode of the source electrode and switch NMOS tube N3 of detection NMOS tube N2 connects

Bigger current fusing fuse when grid voltage is high level；It is that breadth length ratio is smaller to detect NMOS tube N2 and switch NMOS tube N3
Metal-oxide-semiconductor.
The ON-OFF control circuit includes switch S1~S4 and storage unit, and connection type is as shown in Figure 1.It is described to deposit
Storage unit has first input end, the second input terminal and output end OUTPUT；Switch S4 is parallel to first input end and second
Between input terminal；Switch S3 is series between the drain electrode and first input end of detection NMOS tube N2；Switch S3 and first input end
Connecting pin be defined as B points；One end of switch S2 is connect with the second input terminal, and the other end of switch S2 connects with one end of switch S1
It connects, the other end of switch S1 is connect with output end OUTPUT, and the connecting pin of switch S1 and switch S2 is defined as the ends INOUT；It is described
One of nor gate NOR input terminals are connect as Enable Pin EN, another input terminal with B points；Switch S3 and switch NMOS

Detect the grid connection of NMOS tube N2, one of fuse trim the detection NMOS tube N2 in control circuit grid and another
Fuse trims the A points connection of control circuit.
In the present embodiment, it is closed when switch input signal is high, switch disconnects when switch input signal is low；The letter of S3
Number with switch the N3 grid signals of NMOS tube it is identical；Storage unit is enabled when S4 is closed, and storage unit latch data can simultaneously incite somebody to action
It is constant that data remain to output end OUTPUT, while data remaining to B points are constant, and memory module does not work when S4 is disconnected.
The present invention also provides the control methods that a kind of multifunctional low power consumption fuse trims control circuit, including：
1) it initializes, the fuse data of A points is directly read into B points and output end OUTPUT is remained to by storage unit
It is constant；
2) data are written, B points are write data by control switch and pass through, are held data in by storage unit
B points and output end OUTPUT are constant.
3) data are read, are read data from the ports INOUT by controlling switch；
4) true fusing decides whether the fuse that fuses according to write-in data by EN.
Specifically,
1. the low-power consumption of fuse is read
Before every task, needs to be read out the data of fuse, that is, initialize fuse data.
Attached drawing 3 is the sequence diagram for initializing fuse.Switch S1~S4 action, at this time S1, S2 disconnect, data can not be written with
It reads.S3 is closed at the T1 moment, while S4 is disconnected by being closed into, and storage unit does not work at this time, reads A point datas.In T2
It carves S3 to be disconnected by being closed into, S4 is re-closed by being disconnected to simultaneously, and storage unit works and A point datas are maintained at output end
OUTPUT is constant, and fuse data is exported from output end OUTPUT at this time.When S3 is high level, S5 is high level at this time, by electricity
Source has by fuse FUSE positive and negative terminals, detection NMOS tube N2 hourglass source electrodes, switch NMOS tube N3 hourglass source electrodes to ground access, will produce
Electric current, but the reading fuse data time is short (6ns), and data can be held output end OUTPUT, while realize extremely low power dissipation.
2. the low-power consumption of data is written
Attached drawing 4 is the low-power consumption write timing figure of data.By being disconnected to closure, (closing time can basis at the T3 moment by S2
External clock length controls, and can pass through and control closing time length and control power consumption), while S4 is disconnected by being closed into, data
It is written to B points.When data write-in finishes, T4 moment S2 disconnects, S4 is closed, and storage unit is enabled to keep write-in B point datas simultaneously
It is constant that B point datas are maintained at output end OUTPUT, data are written at this time to be exported from output end OUTPUT.Since number is written
It can be usually controlled within 1us according to the practical control of circuit, the time according to the time, when S2 is high level, S5 is at this time
High level, S3 are low level, are not had to ground access by fuse FUSE by power end, so write-in data can realize extremely low work(
Consumption.
3. the low-power consumption of data is read
Attached drawing 5 is the low-power consumption readout sequence figure of data.The write-in of data is divided into two steps, and S2, S3, S4 are disconnected.T5
Moment S1 is closed that (closing time can be controlled according to external clock length, and can allow in speed can be with by being disconnected to
This time is shortened to reduce power consumption, to control power consumption by controlling closing time length).After data are read, when T6
It carves S1 to disconnect, data are read from the ends INOUT.In reading data procedures, not by power end by fuse FUSE to access,
So extremely low power dissipation can be realized by reading data.
4. true fusing operation
True fusing controls signal by carrying out fusing operation to fuse, realize it is state cured, signal it is permanent defeated
Go out.The ends EN of NOR are often high before true fusing, i.e. N1 grids input is often low, and fuse does not fuse.After true melt data is written,
Data are maintained at B points, the i.e. one end NOR by storage unit.Start true fusing operation when EN is low level, when true melt data
For high level when, NOR output be it is low, fuse does not fuse, after solidification A point datas be high level；When true melt data is low electricity
Usually, NOR outputs are height, and fuse failure, A point datas are low level after solidification.Repetitive operation fuse initialization data after solidification
When read solidification after data.
5. outside low-power consumption difference fuse way of realization
External low-power consumption difference fuse way of realization such as attached drawing 2.Such as 10 low-power consumption of M1 and M2 inside modules structure are multi-functional
Fuse trimming module, M1 modules As point are connected to the ends S5 of other side, the i.e. switch of 10 modules with M2 modules As point by difference form
The grid of NMOS tube N2.M1 modules do not export, but as write-in data, preserve data, read data and use；M2 modules are in this base
Output is also used as on plinth to use.When not having to initialize fuse, the grid of S5 connecting valve NMOS tubes N2, S3 is disconnected, and is not had
Have from power supply to ground access, does not consume power consumption.When needing very fusing solidification fuse data, when M2 modules need output 1, then melt
Disconnected M1 module fuses are low level always for the i.e. grids of switch NMOS tube N2 of its S5 of M2 modules, in the initialization fuse time difference
Divide fuse only to have M1 modules and will produce an access from power supply to ground；When M2 modules need output 0, then fuse M2 modules
Fuse is always low level for the i.e. grids of switch NMOS tube N2 of its S5 of M1 modules, the difference fuse when initializing fuse
It has M2 modules and will produce an access from power supply to ground, only there are one modules to consume power consumption for both of which, compares more
Half power consumption is only consumed in traditional structure, realizes more low power consumption operation.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, it is clear that those skilled in the art
Various changes and modifications can be made to the invention by member without departing from the spirit and scope of the present invention.If in this way, the present invention
Within the scope of the claims of the present invention and its equivalent technology, then the present invention is also intended to include these these modifications and variations
Including modification and variation.
